下呼吸道疾病是儿科常见病,研究发现小儿时期机体免疫功能低下,尤其是呼吸道局部免疫功能低下与呼吸道疾病的发生有密切关系。SIgA是机体局部抗感染免疫的重要因素之一,为此我们对86例下呼吸道疾病、包括肺炎、毛细支气管炎(毛支)、哮支、哮喘症的急性期及恢复期检测了唾液中SIgA含量,现报告如下。 Lower respiratory tract disease is a common pediatric disease, the study found that childhood immune dysfunction, especially respiratory tract local immune dysfunction and respiratory disease are closely related. SIgA is one of the most important factors in local anti-infective immunity. For this reason, SIgA in saliva was detected in 86 cases of lower respiratory tract diseases, including pneumonia, bronchiolitis (bronchiolitis), asthma, and acute and convalescent asthma Content, the report is as follows.
